A recent study published in JAMA Network Open analyzed over 520,000 hospitalized patients with nonsevere COVID-19 and found that routine early antibiotic treatment provided no clinically significant benefits.

The research indicates that the use of antibiotics in these cases may be unnecessary, particularly given the associated risks of adverse outcomes.

The cohort studied had a median age of 66 years, with notable representation of Black (17.8%) and Hispanic (12.2%) patients.

Among these patients, 30.8% received antibiotics for community-acquired pneumonia upon admission, with an average hospital stay of four days and a 7.9% readmission rate within 30 days.

Antibiotic treatment was linked to increased odds of poor clinical outcomes, as evidenced by a statistically significant odds ratio of 1.03 and a weighted odds ratio of 1.10 for mortality.

Clinical deterioration occurred in 20.8% of patients treated with antibiotics compared to 18.4% of those who did not receive them, but this difference was not clinically significant.

Despite only 5% of these COVID-19 cases involving confirmed bacterial co-infections, antibiotic use among hospitalized patients exceeded 30%, raising concerns about antibiotic stewardship.

Patients receiving antibiotics also underwent more diagnostic tests and COVID-19 treatments on their first day of admission compared to those who did not.

The World Health Organization has underscored the critical global health threat posed by antimicrobial resistance, highlighting the dangers of antibiotic misuse.

This study emphasizes the need to reevaluate antibiotic prescribing practices in the management of COVID-19.

The authors advocate for implementing antibiotic stewardship strategies to ensure appropriate use among patients with nonsevere COVID-19.

The study faced limitations, including potential residual confounding and reliance on administrative data for COVID-19 diagnoses without a prespecified protocol.
